Q: How long can you drive on a leak in the head gasket at cylinder 2 and 3? on 2003 BMW X5

The dealership told me that it would cost $4242 to reseal with a head test. But if the cylinder head have to be replaced it will cost 6811. If they can torque it back on if not then I will need a new engine. What do you think? The truck has 148,000 miles on it

ask any independent BMW specialty shop and if he's worth a penny, he will tell you to go ahead and put in a used
engine. an engine is less labor than a head gasket. if you go the head gasket route there is no guarantee that the block is okay----so, you've spent all that money and then you have to buy the engine ANYWAY. of course, there is the other question: what caused it to overheat in the
first place? radiator? water pump? all that must be fixed
as well no matter which route you take. (note: this not
unusual for a BMW; they cannot be overheated and survive)
